Abstract (en)
Color dither patterns are read into a pixel bit map memory used to form a color display by means of concurrently addressing a pattern memory storing the dither patterns. Lower order address bits repeatedly access a preselected portion of the pattern memory to supply the dither pattern which is written as data into the pixel bit map memory.
